Setup Display Brightness Configuration:
Step 6
:
The PNL10 automatically controls the display brightness for optimal visibility under all
ambient lighting conditions. The ambient light is sampled by a built in light sensor
located on the front face of the PCB or by an optional external light sensor wired to the
AUX connector. A control algorithm computes the optimal brightness and adjusts the
average LED current via a PWM circuit. PWM circuit is designed to prevent flicker and
color distortion.
You may chose to bias automatic brightness control algorithm towards saving battery
(Battery Life Optimized) or making the display brighter and hence more noticeable
(Brightness Optimized).
In the “Battery Life Optimized” setting the display brightness is reduced by about 30%
from the factory default setting for any ambient lighting condition. This can be
particularly advantageous for portable signs operating solely off a battery and allow the
sign to operate up to 30% longer under heavy traffic conditions. If you find the display
brightness in-adequate then set the display to “Brightness Optimized”.
Setup Operating Mode Configuration:
Step 7
:
For normal operation of the sign on the road select “Normal Operation”. In this mode the
radar will pickup actual targets in front of the unit and display them on the digits if they
range between the Minimum Display Limit and Maximum Display Limit.
The PNL10 also supports a “Demo Mode”. In this mode, the radar generates a pre-
programmed sequence of speeds and shows them on the display. Note that the speed
limits still apply to these speeds, so selecting different limits will change what speeds are
displayed and if the strobe is activated. The ambient light sensor and automatic display
